This invention relates to a .new and improved shifting plate for loose leafjbin'ders.

"placed upon the of a, business or other enterprise, it'is' frequently necessary to transfer portions of the sheets ina loose 'leaf' binder to another loose leaf binder. In order'ito do this, it is of course, necessary to open'thef prongs, rings or postso'f the binder to perm t the removal therefrom of the sheets which it is desired to transfer. It is also, of course,necessary to then open thebinder to which the sheets are to "be transferred so that the .same'maybe prongs, rings or posts of the second hinder.v

Inasmuch as loose leaves are confined a binder by virtue or" the'fact that they are'provided with apertures along (one edge through which the prongs or rings of the binder extend, it is necessary, when inserting a sheet or sheets into a binder that the apertures in the sheets he placed in exact registration with the prongs or rings which are to receive them.

in the case of a single sheet, this is comparatively an easy procedure, but when it is desired to place a plurality of sheets in a binder, it is diflioul't to manually arrange all of the sheets so that corresponding apertures in the sheets will be in registrationwith each other to permit the passage therethrough of the prongs or rings of the binder into which they are to be placed.

The main object of my invention is to provide a device by the use of which a plurality of sheets may be removed from a binder and maintained with the corresponding apertures in the sheets in registration, so that such sheets may be placed upon the prongs or rings of a second binder with a minimum of effort and care.

Another object is to provide a device to aid in transferring sheets from onerbinder to another, which may be used with diflerent types of binders if desired.

Other objects and advantages relate to the size, shape and arrangement of parts, all as Willmore fully appear from the following description' taken in connection with the accompanying drawings, in which:

9 on member 7 in longitudinally spaced relation. Prongs 8 are in staggered relation to prongs 9.

The binder 5 is also provided with a cover 10 hingedly connected to back member 7, and with an opposing cover 11 hingedly connected to back member 6. I also show in position on prongs 9 a plurality of loose leaves 12. The loose leaves 12 are provided on. one edge with a plurality of apertures 13, in longitudinally spaced relation, and so positioned as to permit the passage therethrough of prongs 9 and prongs 8 when the book is in the closed position.

lVhen it is desired to transfer sheets 12 on binder 5 to another binder, not shown, binder 5 is opened to the position shown in Figure 4. The shifting plate 1 with the posts 3 extending downwardly is then placed in position on the uppermost of sheets 12, with the posts 3 extending downwardly into apertures 13 and with the prongs 9 extending upwardly through certain of the apertures l. When the shifting plate 1 is in the last-described position, the operator grasps the leaves 12 which he desires to transfer and holds them in juxtaposition and with the topmost one against the under surface of shifting plate 1. The loose leaves 12 and the shifting plate 1 are then raised simultaneously upwardly off of the prongs 9 and are then carried to a second loose leaf binder, which has been placed in the open position to receive the sheets 12. The prongs of the second binder, not shown, are then inserted through apertures 13 in loose leaves 12 and through apertures 4 in shifting plate 1 and the loose leaves 12 allowed to move downwardly on such prongs. The shifting plate 1 is then moved upwardly from the prongs of the second binder and the prongs of the second binder are then moved to the closed position.

It will be appreciated that when a plurality of loose leaves 12 are on the posts 3 of shifting plate 1 they may be moved from place to place retaining the corresponding apertures 13 in the loose leaves 12 always in registration, .so that the insertion into them of the prongs of a binder, in one operation, is comparatively simple and easy.

It will also be appreciated that the numher and arrangement of the posts 3 on the shifting plate 1 may be varied as desired, as may the number and position of the apertures 1 in shifting plate 1.

It will also be appreciated that by the proper positioning of posts 3 and apertures in shifting plate 1 the shifting plate 1 may be adapted to be used with dilferent types of binders, whether prong, ring or posts.

It will also be appreciated that the length and exact shape of the posts 3 may be varied depending upon the maximum number of loose leaves 12 which it may be desired to transfer in one operation.

It will also be understood that the materials of which my shifting plate are made may be varied to a considerable extent, for although I have shown and described a specific structure and form of parts, as illustrative of an embodiment of my invention, I do not desire to restrict myself to the exact size, shape or relation of parts as various changes may be made within the scope of the appended claims.

I claim:

1. In a device of the class described, a substantially fiat body portion, a plurality of vertically extending posts aflixed to one edge of the body portion in spaced relation and adapted to enter apertures in loose leaves, and said body portion having apertures with unbroken edges near one edge in alignment with the posts and adapted to receive the prongs of a loose leaf binder.

2. In a device of the class described, a substantially flat body portion, a plurality of vertically extending posts aflixed to one edge of the body portion in spaced relation and adapted to enter apertures in loose leaves, and said body portion having a plurality of apertures with unbroken edges near one edge and intermediate adj acent posts and in alinement therewith and adapted to receive the prongs of a loose leaf binder.

In witness whereof I have hereunto set my hand this 14th day of March, 1929.
